Detecting and preventing network slice failure for 5G or other next generation network

ABSTRACT

Network slicing can provide logical network partitioning. This introduces a high degree of flexibility to support devices with different requirements in terms of quality of service, as well as to optimize the network usage. However, each one of these networks can be used for distinct business purposes. Thus, individual slice surveillance statistics, including failure messages, can be utilized to alert other slices that share the same infrastructure. Thus, an early recovery action can be prompted based on a single slice&#39;s anomalies being shared with other slices.

TECHNICAL FIELD

This disclosure relates generally to facilitating detection of network slice failure. For example, this disclosure relates to facilitating detecting and preventing network slice failure of network slices sharing resources for a 5th generation (5G), or other next generation network, air interface.

BACKGROUND

5th generation (5G) wireless systems represent a next major phase of mobile telecommunications standards beyond the current telecommunications standards of 4^(th) generation (4G). Rather than faster peak Internet connection speeds, 5G planning aims at higher capacity than current 4G, allowing a higher number of mobile broadband users per area unit, and allowing consumption of higher or unlimited data quantities. This would enable a large portion of the population to stream high-definition media many hours per day with their mobile devices, when out of reach of wireless fidelity hotspots. 5G research and development also aims at improved support of machine-to-machine communication, also known as the Internet of things, aiming at lower cost, lower battery consumption, and lower latency than 4G equipment.

The above-described background relating to facilitating detecting and preventing network slice failure of network slices sharing resources is merely intended to provide a contextual overview of some current issues, and is not intended to be exhaustive. Other contextual information may become further apparent upon review of the following detailed description.

It should be noted that although various aspects and embodiments have been described herein in the context of 5G, Universal Mobile Telecommunications System (UMTS), and/or Long Term Evolution (LTE), or other next generation networks, the disclosed aspects are not limited to 5G, a UMTS implementation, and/or an LTE implementation as the techniques can also be applied in 3G, 4G or LTE systems. For example, aspects or features of the disclosed embodiments can be exploited in substantially any wireless communication technology.

Additionally, substantially all aspects disclosed herein can be exploited in legacy telecommunication technologies.

Described herein are systems, methods, articles of manufacture, and other embodiments or implementations that can facilitate detecting and preventing network slice failure of network slices sharing resources for a 5G network. Facilitating detecting and preventing network slice failure of network slices sharing resources for a 5G network can be implemented in connection with any type of device with a connection to the communications network (e.g., a mobile handset, a computer, a handheld device, etc.) any Internet of things (IOT) device (e.g., toaster, coffee maker, blinds, music players, speakers, etc.), and/or any connected vehicles (cars, airplanes, space rockets, and/or other at least partially automated vehicles (e.g., drones)). In some embodiments the non-limiting term user equipment (UE) is used. It can refer to any type of wireless device that communicates with a radio network node in a cellular or mobile communication system. Examples of UE are target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communication, PDA, Tablet, mobile terminals, smart phone, IOT device, laptop embedded equipped (LEE), laptop mounted equipment (LME), USB dongles, etc. The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g. interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception.

In some embodiments, the non-limiting term radio network node or simply network node is used. It can refer to any type of network node that serves a UE or network equipment connected to other network nodes or network elements or any radio node from where UE receives a signal. Non-exhaustive examples of radio network nodes are Node B, base station (BS), multi-standard radio (MSR) node such as MSR BS, eNode B, gNode B, network controller, radio network controller (RNC), base station controller (BSC), relay, donor node controlling relay, base transceiver station (BTS), edge nodes, edge servers, network access equipment, network access nodes, a connection point to a telecommunications network, such as an access point (AP), transmission points, transmission nodes, RRU, RRH, nodes in distributed antenna system (DAS), etc.

Cloud radio access networks (RAN) can enable the implementation of concepts such as software-defined network (SDN) and network function virtualization (NFV) in 5G networks. This disclosure can facilitate a generic channel state information framework design for a 5G network. Certain embodiments of this disclosure can include an SDN controller that can control routing of traffic within the network and between the network and traffic destinations. The SDN controller can be merged with the 5G network architecture to enable service deliveries via open application programming interfaces (“APIs”) and move the network core towards an all internet protocol (“IP”), cloud based, and software driven telecommunications network. The SDN controller can work with, or take the place of policy and charging rules function (“PCRF”) network elements so that policies such as quality of service and traffic management and routing can be synchronized and managed end to end.

5G, also called new radio (NR) access, networks can support the following: data rates of several tens of megabits per second supported for tens of thousands of users; 1 gigabit per second can be offered simultaneously to tens of workers on the same office floor; several hundreds of thousands of simultaneous connections can be supported for massive sensor deployments; spectral efficiency can be enhanced compared to 4G; improved coverage; enhanced signaling efficiency; and reduced latency compared to LTE. In multicarrier systems such as OFDM, each subcarrier can occupy bandwidth (e.g., subcarrier spacing). If the carriers use the same bandwidth spacing, then it can be considered a single numerology. However, if the carriers occupy different bandwidth and/or spacing, then it can be considered a multiple numerology.

A failure in any one of a wireless network slice can be leveraged to predict and prevent failures or major outages in other network slices that share the same and/or common infrastructure. The proposed idea can use analytics enabled real-time streaming of network performance data, such as call detail record (CDR) and service key performance indicators (KPIs), to detect any shared resource anomalies and notify the SDN to alert other slices' management entities about the shared infrastructure failure before the same failure happens in those slices' respective domains. The failure can be mitigated by fixing the root cause or by allowing the slice to migrate to another infrastructure. Early warnings and recovery capabilities can prevent major outages that can result in revenue loss.

Network slicing is one of the key concepts introduced by 5G networks which is designed and intended to provide logical network partitioning. This introduces a high degree of flexibility to support devices with different requirements in terms of quality of service, as well as to optimize the network usage. This flexibility can be achieved with via virtualization techniques by providing independent networks over a shared infrastructure. Each one of these networks can be used for distinct business purposes. This disclosure leverages individual slice's surveillance statistics, including any failure messages, to alert other slices that share the same infrastructure. Thus, in order to take early recovery action, a single slice's anomalies can be shared with other slices.

This concept cab help IoT slicing maintain a high quality of service (QoS). In network slicing, IoT slices can be allocated to different verticals. These verticals can share the same physical infrastructure, comprising: an access network (wireless and/or wireline), a transport network, and/or a core network. The core network can host the equipment with higher capacity, while more constrained computing devices can be installed close to the IoT devices (e.g., sensors and actuators). So, any failure in these components of the physical infrastructure, access, transport, core, can be propagated vertically and affect all of the applications riding on them. From the vertical's perspective, there can be an isolated network infrastructure allocated to them, infrastructure which provide specific functions and performance figures. The industrial IoT slice can be used to connect robots and other devices to an application. But at the most foundational level, the shared infrastructure can be common to all slices such that this disclosure can help by providing predictive surveillance capabilities.

IoT solutions can already allow IoT applications and services sharing amongst several customers (or tenants) and also physical resource sharing. This means that multiple tenants can share the same platform infrastructure (e.g., computational, network and storage resources within a data center, or the like) and/or the IoT devices can send measurements collected from sensors. However, network slicing goes beyond these multi-tenancy bases, since it allows the partitioning of the networks connecting the locations and data centers where virtualized network functions are installed and can avoid any interference between functions allocated to different partitions. Thus, the access transport and core networks can be split into independent logical networks that can be assigned in turn to different customers.

The network slicing concept, including “Internet of Things slicing” already exists for the Fifth Generation (5G) of mobile networks. But the proposed method of leveraging failure in any one of the wireless network slices to predict and prevent failures or major outages in other network slices with same and common infrastructure, does not exist today. Some fundamental building blocks, like Network Function Virtualization (NFV) or Software Define Networking (SDN) are used in network slicing. But the concept of predictive maintenance of all the vertical slices based on the individual slice's health is not available with current 5G slicing solution today. This failure could be prevented by fixing the root cause in the infrastructure or by allowing the slice to migrate to another infrastructure. Thus, this idea is new and noble.

Network slicing introduces a high degree of flexibility to support devices with different requirements in terms of quality of service, as well as to optimize the network usage. This flexibility is achieved with the help of virtualization techniques by providing independent networks over a shared infrastructure. Each one of these networks can be used for distinct business purposes. However, this implies greater complexity for the network owner's operation departments since it is yet another aspect to be configured and maintained. This complexity requires the introduction of a dynamic predictive network slice monitoring capability responsible for considering all the business and technical provisioning and surveillance requirements. This is where the proposed idea will come into play for the E2E QoS of the wireless communication networks, including 5g and beyond (5 GB). This is a simple but very efficient and effective predictive maintenance feature in 5 GB.

This proposed feature considers multi-tenancy aspects at the edge and the core domains along with network slicing at the different transport networks involved in the device-to-edge and end-to-End edge communications. This enables a holistic maintenance view of the slicing concept applied to an IoT solution, where the proposed method is capable of providing the maintenance of required resources (computation, networking, and storage) across all the different domains involved in the execution of wireless communication services.

Slice surveillance statistics can be collected by the slice collector which has connectivity to a cloud device. If something in a vertical slice is wrong (e.g., too many call drops have exceeded a defined threshold), the call data record (CDR) can store this data. This data can then be sent to the analytics component. The analytics component can perform on-the-fly analysis and/or use data from previous slice analysis. Thus, the analytics component can determine if the problem occurring is a common problem or a new problem that the slice is encountering. Based on the problem, the SDN component can perform a mitigation procedure (e.g., reroute traffic, enable/disable slices, enable/disable hardware servicing the slice, rebooting of a virtual network function of the slice, backing up or migrating data to another server, notification of packet travel times, or the like), by instructing the slice network management component to perform the mitigation procedures. If the problem is common to the slices (e.g., the problem is a physical entity), or the problem is local (e.g., local to a particular component of the slice) to a particular slice, then the traffic can be rerouted according to where the problem is.

In one embodiment, described herein is a method comprising receiving, by software-defined networking equipment comprising a processor, resource data representative of a resource, wherein the resource is shared between a first network slice and a second network slice, and wherein the first network slice and the second network slice utilize a same infrastructure. The method can comprise receiving, by the software-defined networking equipment, failure data indicative of a failure of the resource at the first network slice. Furthermore, in response to receiving the failure data and based on a defined rule, the method can comprise sending, by the software-defined networking equipment, notification data representative of a notification of the failure to a server. Additionally, in response to sending the notification data to the server, facilitating, by the software-defined networking equipment via the server, a corrective action to mitigate the failure.

According to another embodiment, a system can facilitate, receiving resource data representative of a resource being shared between a first network slice and a second network slice, wherein the first network slice and the second network slice utilize a first infrastructure. The system can comprise receiving failure data indicative of a failure of the resource at the first network slice. In response to receiving the failure data, the system can comprise determining a cause of the failure. Furthermore, in response to determining the cause of the failure and based on a defined rule, the system can comprise generating message data representative of a message to be communicated to the second network slice. Additionally, in response to generating the message, the system can comprise performing a corrective action to mitigate the failure.

According to yet another embodiment, described herein is a machine-readable medium that can perform the operations comprising receiving resource data representative of a resource shared between a first network slice and a second network slice, wherein the first network slice and the second network slice utilize a first infrastructure to share the resource. The machine-readable medium can perform the operations comprising receiving failure data indicative of a failure of the resource at the first network slice. In response to receiving the failure data, the machine-readable medium can perform the operations comprising determining a cause of the failure. Based on the cause of the failure and a defined rule, the machine-readable medium can perform the operations comprising performing a corrective action to mitigate the failure, wherein the corrective action comprises migrating the second network slice to a second infrastructure to prevent the failure at the second network slice.

These and other embodiments or implementations are described in more detail below with reference to the drawings.

Referring now to FIG. 1, illustrated is an example wireless communication system 100 in accordance with various aspects and embodiments of the subject disclosure. In one or more embodiments, system 100 can include one or more user equipment UEs 102. The non-limiting term user equipment can refer to any type of device that can communicate with a network node in a cellular or mobile communication system. A UE can have one or more antenna panels having vertical and horizontal elements. Examples of a UE include a target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communications, personal digital assistant (PDA), tablet, mobile terminals, smart phone, laptop mounted equipment (LME), universal serial bus (USB) dongles enabled for mobile communications, a computer having mobile capabilities, a mobile device such as cellular phone, a laptop having laptop embedded equipment (LEE, such as a mobile broadband adapter), a tablet computer having a mobile broadband adapter, a wearable device, a virtual reality (VR) device, a heads-up display (HUD) device, a smart car, a machine-type communication (MTC) device, and the like. User equipment UE 102 can also include IOT devices that communicate wirelessly.

In various embodiments, system 100 is or includes a wireless communication network serviced by one or more wireless communication network providers. In example embodiments, a UE 102 can be communicatively coupled to the wireless communication network via a network node 104. The network node (e.g., network node device) can communicate with user equipment (UE), thus providing connectivity between the UE and the wider cellular network. The UE 102 can send transmission type recommendation data to the network node 104. The transmission type recommendation data can include a recommendation to transmit data via a closed loop MIMO mode and/or a rank-1 precoder mode.

A network node can have a cabinet and other protected enclosures, an antenna mast, and multiple antennas for performing various transmission operations (e.g., MIMO operations). Network nodes can serve several cells, also called sectors, depending on the configuration and type of antenna. In example embodiments, the UE 102 can send and/or receive communication data via a wireless link to the network node 104. The dashed arrow lines from the network node 104 to the UE 102 represent downlink (DL) communications and the solid arrow lines from the UE 102 to the network nodes 104 represents an uplink (UL) communication.

System 100 can further include one or more communication service provider networks 106 that facilitate providing wireless communication services to various UEs, including UE 102, via the network node 104 and/or various additional network devices (not shown) included in the one or more communication service provider networks 106. The one or more communication service provider networks 106 can include various types of disparate networks, including but not limited to: cellular networks, femto networks, picocell networks, microcell networks, internet protocol (IP) networks Wi-Fi service networks, broadband service network, enterprise networks, cloud based networks, and the like. For example, in at least one implementation, system 100 can be or include a large scale wireless communication network that spans various geographic areas. According to this implementation, the one or more communication service provider networks 106 can be or include the wireless communication network and/or various additional devices and components of the wireless communication network (e.g., additional network devices and cell, additional UEs, network server devices, etc.). The network node 104 can be connected to the one or more communication service provider networks 106 via one or more backhaul links 108. For example, the one or more backhaul links 108 can include wired link components, such as a T1/E1 phone line, a digital subscriber line (DSL) (e.g., either synchronous or asynchronous), an asymmetric DSL (ADSL), an optical fiber backbone, a coaxial cable, and the like. The one or more backhaul links 108 can also include wireless link components, such as but not limited to, line-of-sight (LOS) or non-LOS links which can include terrestrial air-interfaces or deep space links (e.g., satellite communication links for navigation).

Wireless communication system 100 can employ various cellular systems, technologies, and modulation modes to facilitate wireless radio communications between devices (e.g., the UE 102 and the network node 104). While example embodiments might be described for 5G new radio (NR) systems, the embodiments can be applicable to any radio access technology (RAT) or multi-RAT system where the UE operates using multiple carriers e.g. LTE FDD/TDD, GSM/GERAN, CDMA2000 etc.

For example, system 100 can operate in accordance with global system for mobile communications (GSM), universal mobile telecommunications service (UMTS), long term evolution (LTE), LTE frequency division duplexing (LTE FDD, LTE time division duplexing (TDD), high speed packet access (HSPA), code division multiple access (CDMA), wideband CDMA (WCMDA), CDMA2000, time division multiple access (TDMA), frequency division multiple access (FDMA), multi-carrier code division multiple access (MC-CDMA), single-carrier code division multiple access (SC-CDMA), single-carrier FDMA (SC-FDMA), orthogonal frequency division multiplexing (OFDM), discrete Fourier transform spread OFDM (DFT-spread OFDM) single carrier FDMA (SC-FDMA), Filter bank based multi-carrier (FBMC), zero tail DFT-spread-OFDM (ZT DFT-s-OFDM), generalized frequency division multiplexing (GFDM), fixed mobile convergence (FMC), universal fixed mobile convergence (UFMC), unique word OFDM (UW-OFDM), unique word DFT-spread OFDM (UW DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM, resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like. However, various features and functionalities of system 100 are particularly described wherein the devices (e.g., the UEs 102 and the network device 104) of system 100 are configured to communicate wireless signals using one or more multi carrier modulation schemes, wherein data symbols can be transmitted simultaneously over multiple frequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.). The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g. interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception. Note that some embodiments are also applicable for Multi RAB (radio bearers) on some carriers (that is data plus speech is simultaneously scheduled).

In various embodiments, system 100 can be configured to provide and employ 5G wireless networking features and functionalities. 5G wireless communication networks are expected to fulfill the demand of exponentially increasing data traffic and to allow people and machines to enjoy gigabit data rates with virtually zero latency. Compared to 4G, 5G supports more diverse traffic scenarios. For example, in addition to the various types of data communication between conventional UEs (e.g., phones, smartphones, tablets, PCs, televisions, Internet enabled televisions, etc.) supported by 4G networks, 5G networks can be employed to support data communication between smart cars in association with driverless car environments, as well as machine type communications (MTCs). Considering the drastic different communication demands of these different traffic scenarios, the ability to dynamically configure waveform parameters based on traffic scenarios while retaining the benefits of multi carrier modulation schemes (e.g., OFDM and related schemes) can provide a significant contribution to the high speed/capacity and low latency demands of 5G networks. With waveforms that split the bandwidth into several sub-bands, different types of services can be accommodated in different sub-bands with the most suitable waveform and numerology, leading to an improved spectrum utilization for 5G networks.

To meet the demand for data centric applications, features of proposed 5G networks may include: increased peak bit rate (e.g., 20 Gbps), larger data volume per unit area (e.g., high system spectral efficiency—for example about 3.5 times that of spectral efficiency of long term evolution (LTE) systems), high capacity that allows more device connectivity both concurrently and instantaneously, lower battery/power consumption (which reduces energy and consumption costs), better connectivity regardless of the geographic region in which a user is located, a larger numbers of devices, lower infrastructural development costs, and higher reliability of the communications. Thus, 5G networks may allow for: data rates of several tens of megabits per second should be supported for tens of thousands of users, 1 gigabit per second to be offered simultaneously to tens of workers on the same office floor, for example; several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments; improved coverage, enhanced signaling efficiency; reduced latency compared to LTE.

The 5G access network may utilize higher frequencies (e.g., >6 GHz) to aid in increasing capacity. Currently, much of the millimeter wave (mmWave) spectrum, the band of spectrum between 30 gigahertz (GHz) and 300 GHz is underutilized. The millimeter waves have shorter wavelengths that range from 10 millimeters to 1 millimeter, and these mmWave signals experience severe path loss, penetration loss, and fading. However, the shorter wavelength at mmWave frequencies also allows more antennas to be packed in the same physical dimension, which allows for large-scale spatial multiplexing and highly directional beamforming.

Performance can be improved if both the transmitter and the receiver are equipped with multiple antennas. Multi-antenna techniques can significantly increase the data rates and reliability of a wireless communication system. The use of multiple input multiple output (MIMO) techniques, which was introduced in the third-generation partnership project (3GPP) and has been in use (including with LTE), is a multi-antenna technique that can improve the spectral efficiency of transmissions, thereby significantly boosting the overall data carrying capacity of wireless systems. The use of multiple-input multiple-output (MIMO) techniques can improve mmWave communications, and has been widely recognized a potentially important component for access networks operating in higher frequencies. MIMO can be used for achieving diversity gain, spatial multiplexing gain and beamforming gain. For these reasons, MIMO systems are an important part of the 3rd and 4th generation wireless systems, and are planned for use in 5G systems.

Referring now to FIG. 2, illustrated is an example schematic system block diagram of a network slice according multiple network slices 200 for which failure detection can be accomplished. It should be noted that any number of slices can be utilized and that FIG. 2 is but a depiction of one embodiment. As illustrated, several IoT slices can be allocated to various functions on different verticals. These verticals can share the same physical infrastructure, (e.g., an access network (wireless and/or wireline), a transport network, and/or a core network). The core network can host the equipment with higher capacities, while more constrained computing devices can be installed close to the IoT devices (e.g., sensors and actuators). The proposed solution can make use of this type generic network slice architecture for realization with added network functionalities that are unique to the proposed concept.

The multiple network slices 200 can be dedicated to various functions. For example, an industrial IoT slice can be used to connect robots and other devices to some applications with access to the network. This kind of service can utilize low latency communication, such that functions can be deployed at the edge of the network (e.g., access network). An agriculture IoT slice can be used to monitor and deliver relevant information in smart farming applications (e.g., values of temperature or humidity in different regions of a crop field). In this case, functions able to process high volumes of data can be utilized in nodes allocated in cloud computing infrastructures that are close to the core network. Additionally, an IoT slice can devoted to a healthcare market segment that utilizes devices requiring low latency communications, as well as application processes with high capacity demands, both in terms of computation and storage, which can be satisfied by a cloud computing infrastructure. Furthermore, an IoT slice can be utilized for intelligent transportation systems to connect autonomous cars, as well as other types of connected vehicles, to automotive-specific applications. These applications can utilize the execution of specific functions at the edge, in order to guarantee the execution and actions with strict delay constraints, and/or at the cloud, to support non-sensitive computation tasks and the permanent storage of automotive-related data (e.g., maps, route calculations, etc.). Consequently, although each slice can be utilized to provide different and/or varied functions, the slices can share the same physical infrastructure.

Referring now to FIG. 3, illustrated is an example schematic system block diagram of slice surveillance data collector component according to one or more embodiments.

The slice surveillance data collector component 300 can comprise sub-components (e.g., a reception component 302, a transmission component 304, and a data curation component 306), processor 308 and memory 310 can bi-directionally communicate with each other. It should also be noted that in alternative embodiments that other components including, but not limited to the sub-components, processor 308, and/or memory 310, can be external to the slice surveillance data collector component 300. Aspects of the processor 308 can constitute machine-executable component(s) embodied within machine(s), e.g., embodied in one or more computer readable mediums (or media) associated with one or more machines. Such component(s), when executed by the one or more machines, e.g., computer(s), computing device(s), virtual machine(s), etc. can cause the machine(s) to perform the operations described by the slice surveillance data collector component 300. In an aspect, the slice surveillance data collector component 300 can also include memory 310 that stores computer executable components and instructions.

The slice surveillance data collector component 300 can receive failure data, via reception component 302, from the vertical and horizontal slices of the multiple network slices 200. For example, if the healthcare IoT slice is experiencing a failure, the failure information can be sent to the slice surveillance data collector component 300 and/or the slice surveillance data collector component 300 can request this information at specific defined time intervals. Even a lack of response, from a network slice equipment can be indicative of a network slice failure. After the reception component 302 has received failure information, the failure information can be combined and/or curated at the data curation component 306. The data curation component can segment failure data based on defined criteria such that the process of sending the failure data, via the transmission component 304, to a network management system can be more efficient. The slice surveillance data collector component 300 can also send real time data to the network management component.

Referring now to FIG. 4, illustrated is an example schematic system block diagram of slice network management component according to one or more embodiments.

The network management component 400 can comprise sub-components (e.g., an analysis component 402, an SDN component 404, a failure mitigation component 406), processor 408 and memory 410 can bi-directionally communicate with each other. It should also be noted that in alternative embodiments that other components including, but not limited to the sub-components, processor 408, and/or memory 410, can be external to network management component 400. Aspects of the processor 408 can constitute machine-executable component(s) embodied within machine(s), e.g., embodied in one or more computer readable mediums (or media) associated with one or more machines. Such component(s), when executed by the one or more machines, e.g., computer(s), computing device(s), virtual machine(s), etc. can cause the machine(s) to perform the operations described by the network management component 400. In an aspect, network management component 400 can also include memory 410 that stores computer executable components and instructions.

After the network management component 400 receives the failure data from the slice surveillance data collector component 300, the analytics component 402 can detect anomalies based on previous slice behavior data that can be stored via the analytics component 402. The analytics component 402 can determine the failure and/or the probable cause of the failure. After the analytics component 402 has determined the failure and/or the probable cause of the failure, the analytics component 402 can notify the SDN component 404 to enable the SDN component to 404 to take actions to mitigate failures on one or more slices. For example, the failure mitigation component 406 can perform a mitigation procedure (e.g., reroute traffic, enable/disable slices, enable/disable hardware servicing the slice, rebooting of a virtual network function of the slice, backing up or migrating data to another server, notification of packet travel times, or the like), by instructing the slice network management component 400 to perform the mitigation procedures. If the problem is common to the slices (e.g., the problem is a physical entity), or the problem is local (e.g., local to a particular component of the slice) to a particular slice, then the traffic can be rerouted to avoid the failed slice and/or any additional slices that may be subject to that same type of failure.

Referring now to FIG. 5 illustrates an example schematic system block diagram of slice network management component according to one or more embodiments.

FIG. 5 depicts a system 500 for leveraging failure in any one of the wireless network slices to predict and prevent the same failure in other slices sharing the same physical infrastructure. For instance, several IoT slices can be allocated to different verticals and yet share the same physical infrastructure. The system 500 can comprise the network slices 200, the slice surveillance data collector component 300, and the slice network management component 400. The slice surveillance data collector component 300 can collect vertical and/or horizontal failure data from the network slices 200. The slice surveillance data collector component 300 can then send real time data to the analytics component 402 for anomaly detection. The analytics component 402 can detect anomalies based on previous slice behavior data that can be stored via the analytics component 402. After the analytics component 402 has determined the failure and the probable cause of the failure, the SDN component 404 can failure mitigation component 406 to perform a mitigation procedure based on defined SDN rules.

The slice network management component 400 can then take appropriate actions to mitigate the predicted failures. Alternatively, if the detected problem cannot be fixed, a failed slice can be migrated to one or more other infrastructures for service continuity. For example, the services associated with the agriculture IoT slice can be migrated to another zone that is geographically distinct from the current zone. In another embodiment, if a slice is taken out of service, then some of the services that that slice supports can be picked up by other slices that are not experiencing the problem. For example, if the transport IOT slice needs to be disabled, then the healthcare slice can provide resources to some of the IOT devices that were utilizing resources from the transport IOT slice. This type of support can be managed by the slice network management component 400 by communicating with the various slices.

In order to provide additional context for various embodiments described herein, FIG. 10 and the following discussion are intended to provide a brief, general description of a suitable computing environment 1000 in which the various embodiments of the embodiment described herein can be implemented. While the embodiments have been described above in the general context of computer-executable instructions that can run on one or more computers, those skilled in the art will recognize that the embodiments can be also implemented in combination with other program modules and/or as a combination of hardware and software.

Generally, program modules include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the disclosed methods can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, minicomputers, mainframe computers, Internet of Things (IoT) devices, distributed computing systems, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices.

The illustrated embodiments of the embodiments herein can be also practiced in distributed computing environments where certain tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.

Computing devices typically include a variety of media, which can include computer-readable media, machine-readable media, and/or communications media, which two terms are used herein differently from one another as follows. Computer-readable media or machine-readable media can be any available media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable media or machine-readable media can be implemented in connection with any method or technology for storage of information such as computer-readable or machine-readable instructions, program modules, structured data or unstructured data.

In this regard, the terms “tangible” or “non-transitory” herein as applied to storage, memory or computer-readable media, are to be understood to exclude only propagating transitory signals per se as modifiers and do not relinquish rights to all standard storage, memory or computer-readable media that are not only propagating transitory signals per se.

Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium.

Communications media typically embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communication media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.

With reference again to FIG. 10, the example environment 1000 for implementing various embodiments of the aspects described herein includes a computer 1002, the computer 1002 including a processing unit 1004, a system memory 1006 and a system bus 1008. The system bus 1008 couples system components including, but not limited to, the system memory 1006 to the processing unit 1004. The processing unit 1004 can be any of various commercially available processors. Dual microprocessors and other multi-processor architectures can also be employed as the processing unit 1004.

The system bus 1008 can be any of several types of bus structure that can further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory 1006 includes ROM 1010 and RAM 1012. A basic input/output system (BIOS) can be stored in a non-volatile memory such as ROM, erasable programmable read only memory (EPROM), EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer 1002, such as during startup. The RAM 1012 can also include a high-speed RAM such as static RAM for caching data.

The computer 1002 further includes an internal hard disk drive (HDD) 1014 (e.g., EIDE, SATA), one or more external storage devices 1016 (e.g., a magnetic floppy disk drive (FDD) 1016, a memory stick or flash drive reader, a memory card reader, etc.) and an optical disk drive 1020 (e.g., which can read or write from a CD-ROM disc, a DVD, a BD, etc.). While the internal HDD 1014 is illustrated as located within the computer 1002, the internal HDD 1014 can also be configured for external use in a suitable chassis (not shown). Additionally, while not shown in environment 1000, a solid state drive (SSD) could be used in addition to, or in place of, an HDD 1014. The HDD 1014, external storage device(s) 1016 and optical disk drive 1020 can be connected to the system bus 1008 by an HDD interface 1024, an external storage interface 1026 and an optical drive interface 1028, respectively. The interface 1024 for external drive implementations can include at least one or both of Universal Serial Bus (USB) and Institute of Electrical and Electronics Engineers (IEEE) 1394 interface technologies. Other external drive connection technologies are within contemplation of the embodiments described herein.

The drives and their associated computer-readable storage media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer 1002, the drives and storage media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable storage media above refers to respective types of storage devices, it should be appreciated by those skilled in the art that other types of storage media which are readable by a computer, whether presently existing or developed in the future, could also be used in the example operating environment, and further, that any such storage media can contain computer-executable instructions for performing the methods described herein.

A number of program modules can be stored in the drives and RAM 1012, including an operating system 1030, one or more application programs 1032, other program modules 1034 and program data 1036. All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM 1012. The systems and methods described herein can be implemented utilizing various commercially available operating systems or combinations of operating systems.

Computer 1002 can optionally include emulation technologies. For example, a hypervisor (not shown) or other intermediary can emulate a hardware environment for operating system 1030, and the emulated hardware can optionally be different from the hardware illustrated in FIG. 10. In such an embodiment, operating system 1030 can include one virtual machine (VM) of multiple VMs hosted at computer 1002. Furthermore, operating system 1030 can provide runtime environments, such as the Java runtime environment or the .NET framework, for applications 1032. Runtime environments are consistent execution environments that allow applications 1032 to run on any operating system that includes the runtime environment. Similarly, operating system 1030 can support containers, and applications 1032 can be in the form of containers, which are lightweight, standalone, executable packages of software that include, e.g., code, runtime, system tools, system libraries and settings for an application.

Further, computer 1002 can be enable with a security module, such as a trusted processing module (TPM). For instance with a TPM, boot components hash next in time boot components, and wait for a match of results to secured values, before loading a next boot component. This process can take place at any layer in the code execution stack of computer 1002, e.g., applied at the application execution level or at the operating system (OS) kernel level, thereby enabling security at any level of code execution.

A user can enter commands and information into the computer 1002 through one or more wired/wireless input devices, e.g., a keyboard 1038, a touch screen 1040, and a pointing device, such as a mouse 1042. Other input devices (not shown) can include a microphone, an infrared (IR) remote control, a radio frequency (RF) remote control, or other remote control, a joystick, a virtual reality controller and/or virtual reality headset, a game pad, a stylus pen, an image input device, e.g., camera(s), a gesture sensor input device, a vision movement sensor input device, an emotion or facial detection device, a biometric input device, e.g., fingerprint or iris scanner, or the like. These and other input devices are often connected to the processing unit 1004 through an input device interface 1044 that can be coupled to the system bus 1008, but can be connected by other interfaces, such as a parallel port, an IEEE 1394 serial port, a game port, a USB port, an IR interface, a BLUETOOTH® interface, etc.

A monitor 1046 or other type of display device can be also connected to the system bus 1008 via an interface, such as a video adapter 1048. In addition to the monitor 1046, a computer typically includes other peripheral output devices (not shown), such as speakers, printers, etc.

The computer 1002 can operate in a networked environment using logical connections via wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 1050.

The logical connections depicted include wired/wireless connectivity to a local area network (LAN) 1054 and/or larger networks, e.g., a wide area network (WAN) 1056. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which can connect to a global communications network, e.g., the Internet.

When used in a LAN networking environment, the computer 1002 can be connected to the local network 1054 through a wired and/or wireless communication network interface or adapter 1058. The adapter 1058 can facilitate wired or wireless communication to the LAN 1054, which can also include a wireless access point (AP) disposed thereon for communicating with the adapter 1058 in a wireless mode.

When used in a WAN networking environment, the computer 1002 can include a modem 1060 or can be connected to a communications server on the WAN 1056 via other means for establishing communications over the WAN 1056, such as by way of the Internet. The modem 1060, which can be internal or external and a wired or wireless device, can be connected to the system bus 1008 via the input device interface 1044. In a networked environment, program modules depicted relative to the computer 1002 or portions thereof, can be stored in the remote memory/storage device 1052. It will be appreciated that the network connections shown are example and other means of establishing a communications link between the computers can be used.

When used in either a LAN or WAN networking environment, the computer 1002 can access cloud storage systems or other network-based storage systems in addition to, or in place of, external storage devices 1016 as described above. Generally, a connection between the computer 1002 and a cloud storage system can be established over a LAN 1054 or WAN 1056 e.g., by the adapter 1058 or modem 1060, respectively. Upon connecting the computer 1002 to an associated cloud storage system, the external storage interface 1026 can, with the aid of the adapter 1058 and/or modem 1060, manage storage provided by the cloud storage system as it would other types of external storage. For instance, the external storage interface 1026 can be configured to provide access to cloud storage sources as if those sources were physically connected to the computer 1002.

The computer 1002 can be operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, store shelf, etc.), and telephone. This can include Wireless Fidelity (Wi-Fi) and BLUETOOTH® wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.

The computer is operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, restroom), and telephone. This includes at least Wi-Fi and Bluetooth™ wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.

Wi-Fi, or Wireless Fidelity, allows connection to the Internet from a couch at home, a bed in a hotel room, or a conference room at work, without wires. Wi-Fi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE 802.11 (a, b, g, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps (802.11a) or 54 Mbps (802.11b) data rate, for example, or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic 10BaseT wired Ethernet networks used in many offices.
